Summary of NASA Wake and Weather Data Collection at Memphis International Airport: 2013-2015

摘要

NASA has collected a large dataset of wake vortex and weather observations at Memphis International Airport. The wake data consists primarily of vortices generated between one and two wingspans above the ground. Most of the landings in the dataset include all the required environmental and aircraft data needed for input into fast-time wake vortex prediction models; including vertical profiles of wind speed, air temperature and eddy dissipation rate, as well as the aircraft weights and approach speed. Prior to the collection of this data set there was only a small amount of data that could be used in the evaluation of the skill of fast-time wake vortex prediction models when the vortices were generated within a couple wingspans of the ground surface. This new data set significantly increases the amount of data available for the assessment of the models in this important region. In this paper, we will describe the new data set including how the environmental data was collected and analyzed, and show example results comparing wake vortex behavior for different atmospheric conditions and aircraft types.
